Abstract
The present invention provides a touch panel substrate capable of preventing a detection circuit from being broken down due to application of electrostatic voltage. The touch panel substrate includes a flexible substrate (20) for electrically connecting sensor electrodes (12) and a touch controller (32) to each other. The flexible electrode (20) has one end connected to a terminal section (13) including terminals. The touch panel substrate is further provided with a shielding electrode (14), on an outer side of the terminal section (13).
Claims6
